[0002] The existing rivet guns used for rivet thread lifting sleeves and rivet studs are generally driven by gas-liquid superchargers, which require a pump or air compressor, making them inconvenient to use. In addition, the existing rivet guns have no way to detect pressure during rivet operation.

[0003] Therefore, based on the above-mentioned defects of the existing rivet gun, it is necessary to improve the existing rivet gun. Utility Model Content

The screw nut is located at the upper end of the tension sensor, and the lower end of the tension sensor is covered with a movable sleeve, so that the pressure value can be detected by the tension sensor, which is very convenient.

[0009] Furthermore, the transmission rod passes through the screw rod and the movable sleeve and is connected to a threaded section, the threaded section is located below the movable sleeve, the threaded section is threadedly connected to a threaded lifting sleeve, and the threaded lifting sleeve drives the rivet rod, thereby realizing that the transmission rod drives the rivet rod to rotate and lift.

[0010] Furthermore, the first motor and the second motor are installed vertically on the fixing plate, and the overall structure is compact.

[0011] Furthermore, the threaded section and the threaded lifting sleeve are installed in the fixed sleeve to ensure that the threaded lifting sleeve can move smoothly.

[0012] Furthermore, the fixed sleeve is provided with a lower fixing seat, the movable sleeve is provided with an upper fixing seat, the lower fixing seat is located below the upper fixing seat, and the lower fixing seat and the upper fixing seat are fixedly connected to ensure that the rivet rod and the transmission rod remain coaxial to avoid jamming.

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] See Figure 1 —— Figure 4The present utility model comprises an upper fixed plate 1, a first motor 2, a second motor 3, a fixed sleeve 9, and a rivet rod 10. An upper accommodating box 4 and a lower accommodating box 5 are disposed above the upper fixed plate 1. A first belt drive pulley 11 is mounted within the upper accommodating box 4, and a second belt drive pulley 12 is mounted within the lower accommodating box 5. The first motor 2 is a servo motor. The first and second motors 2 and 3 are mounted perpendicular to the upper fixed plate 1. The first motor 2 drives the first belt drive pulley 11, while the second motor 3 drives the second belt drive pulley 12. The first and second belt drive pulleys 11 and 12 are coaxially arranged.

[0023] The second belt drive pulley 12 of the present invention coaxially drives a screw 14. Screw 14 passes through the upper fixed plate 1 and is then sleeved with a screw nut 17 and a tension sensor 15. Screw nut 17 is located at the upper end of tension sensor 15. A movable sleeve 16 is sleeved at the lower end of tension sensor 15. The tension sensor 15, movable sleeve 16, and screw nut 17 are fixed together.

[0024] The first belt drive wheel 11 of the utility model coaxially drives a transmission rod 13, which passes through the screw rod 14 and the movable sleeve 16 to connect the threaded section 18. The threaded section 18 is fixed below the movable sleeve 16. The threaded section 18 is threadedly connected to a threaded lifting sleeve 19, which drives the rivet rod 10.

[0025] The threaded section 18 and the threaded lifting sleeve 19 of the present invention are installed in the fixed sleeve 9.

[0026] The fixed sleeve 9 of the present invention is provided with a lower fixed seat 7 on its outer sleeve, and the lower fixed seat 7 is mounted on the external frame. The movable sleeve 16 is provided with an upper fixed seat 8 on its outer sleeve, and the lower fixed seat 7 is located below the upper fixed seat 8. The lower fixed seat 7 and the upper fixed seat 8 are fixedly connected. The fixed seat 7 and the upper fixed seat 8 form a floating device, which can stabilize the longitudinal position of the movable sleeve 16 and the fixed sleeve 9, and avoid the situation where the rivet rod 10 is stuck when moving longitudinally.

[0027] An outer cover 6 is installed between the upper fixing plate 1 and the upper fixing seat 8 of the present invention. The lower part of the screw rod 14 , the tension sensor 15 , the movable sleeve 16 , and the screw rod nut 17 are located inside the outer cover 6 .

[0028] The first motor 2 of the present invention drives the transmission rod 13 to rotate, and the transmission rod 13 drives the threaded section 18 and the rivet rod 10 to rotate. When the threaded section 18 rotates, it drives the threaded lifting sleeve 19 to generate longitudinal lifting movement, and the threaded lifting sleeve 19 drives the rivet rod 10 to generate longitudinal lifting movement.

[0029] The second motor 3 of the present invention drives the screw 14 to rotate, thereby causing the tension sensor 15, the movable sleeve 16, and the screw nut 17 to rotate up or down, driving the threaded section 18, the threaded lifting sleeve 19, and the rivet rod 10 to rise or fall.

[0030] The fixing sleeve 9 of the present invention is also provided with a spring for resetting the rivet, which will not be described in detail here.

[0031] The utility model has the following features: tension monitoring, displacement monitoring, angle adjustment, and a floating device in the riveting process capable of self-adaptively adjusting the gun body to release deformation stress.

[0032] Of course, the embodiments described above are only preferred examples of the present invention and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structure, features and principles described in the scope of the patent application of the present invention should be included in the scope of the patent application of the present invention.
